My Musing – At first blush, this is a somewhat curious statement, at least to me. If we strive to keep our conscience clear before God (a high standard indeed), why would we need to concern ourselves about man. Wouldn’t satisfying the former, automatically satisfy the other? It is clear that keeping our conscience clear before God is our top priority and that keeping our conscience clear before man should not take precedence. But the former does not exclude the latter.
Paul states elsewhere to be careful to do what is right in the eyes of all people, and if possible, as far as it depends upon us, we should be a peace with all men. (Romans 12:17-18). Man is fickle, while God is not. So a clear conscience before God will not always satisfy man. Especially if they do not have a relationship with Christ and their only picture of him comes from us. But we must still strive to have a clear conscience, “as far as it depends on us.“
The first (and greatest) commandment is to love God (with heart, soul, mind and strength). We need a clear conscience about that. But is second is like it. Love your neighbor as yourself. (Matthew 22:37-39). We need to keep our conscience clear about that as well.
My Advice – Sleep well with a clear conscience.
